So I just recently finished this one from Daniel Immerwahr. I think I was expecting something a bit more interested in exploring American imperial power in the the non-territorial ways it is expressed.
However, the book was pretty much laser focused on all the physical territorial claims and outposts that the US has had over its history, from territories & colonies, to small military bases. A lot of time spent discussing the Philippines and Puerto Rico, reasonably so.
Because of this, it does miss some of the ways the US has imposed its imperial will over the years, e.g. in South America where it has never had any large explicit territorial claims despite long influencing the political trajectory of the region. I think this and similar things left out are probably the major shortcoming. I really wish it had included the way the US influences other nations through mechanisms that aren't explicitly physical occupation.
The style was also kinda weird to me. It was written in a very Good Morning America voice, for lack of a better term. It is very easy to read, but the tone just seems a little too "You'll never believe what's next" the whole way through in a way that grates after a while.
Still, overall a pretty interesting book. I learned a good deal, especially about the Pacific, including lots of stuff around the time of WW2.
